Security
Overall Crime and Safety
Petty crime, such as pickpocketing and purse snatching, occurs. There have been reports of theft from vehicles, especially rental cars. Armed robberies and tourists being followed by people on motorcycles have also been reported. Burglaries and break-ins are common at resorts, beach houses, and hotels.
Specific areas of concern:
Petty Theft
The main tourist areas are generally safe, but you should take normal precautions. Avoid remote areas at night. Don’t take valuables to the beach. Make sure purses and backpacks are closed and not easy to grab.
Drugs
Used as drug passageway from South America to Europe and North America. Don’t leave bags unattended or agree to carry a package for anyone.
The Airport
The tiny airport is popular with people who like to gather to see planes taking off literally a few feet above their heads. Be aware that getting too close can expose you to jet fumes and the strong winds from the back of a plane can throw you around violently.
Maritime Issues:
Locked dinghy and outboard thefts continue to be a problem in the lagoon, particularly on the French side. Be sure to lift and chain and lock your dinghy and outboard at night and sleep with your doors and hatches locked.
The Caribbean Safety and Security Net provide information by anchorage or by the island. If you experience a boarding, robbery or attack on your yacht or have information about a yachting-related security incident, go to the CSSN homepage and click on the “Report an Incident” icon.
